Product Description:

The MAC063A-0-ES-4-C/095-B-0/WI634LX/S001 is an AC servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it delivers regulated torque and speed to indexing tables, winders, and other motion axes in industrial automation. The unit is supplied without a blocking brake, so external clamping or drive torque must hold the load when power is removed. Its feedback arrangement supports closed-loop velocity and position control, allowing the motor to serve applications that need steady speed regulation and repeatable movement.

A centering diameter of 95 mm aligns the flange with gearbox or machine housings for accurate installation. The shaft uses a DIN 6885 keyway for positive torque transmission through keyed couplings. Under rated excitation, the rotor can reach 3500 rpm, which supports high surface speeds in compact equipment. Heat is removed by natural convection, so no forced-air ducting is required. Power conductors exit through a connector on side B, which can simplify cable routing when the rear side of the motor faces the cabinet. This version also includes a standard-quality tachogenerator for stable analog speed feedback.

The motor is built in size 063 with length class A, giving it a compact envelope for machines that need moderate continuous torque without a larger mounting footprint. Winding code ES indicates the electrical characteristics expected by the matching analog drive. The tachogenerator produces 1.5 V/1000 rpm, providing a linear voltage signal that follows motor speed. An integrated incremental encoder supplies digital position pulses for finer motion control, which is useful when the axis must coordinate speed regulation with accurate positioning. This combination of analog and digital feedback supports both velocity control and repeatable axis movement in general industrial service.
